A novel starch-based composition includes: (a) at least 45% by weight of at least one soluble starch, (b) at most 55% by weight of at least one non-biodegradable, non-amylaceous polymer, and (c) a bonding agent carrying at least two functional groups capable of reacting with molecules carrying functions including an active hydrogen, these amounts being expressed with respect to solids and relative to the sum of (a) and (b). A method for preparing such a starch-based composition and a thermoplastic composition prepared by heating such a composition are also described.

Thermoplastic compositions based on soluble starch and method for preparing such compositions

A thermoplastic or elastomeric composition, is characterized in that: a) it exhibits a degree of biodegradability of less than 50%, preferably less than 30%, and b) it contains at least 0.5% and at most 99.95% by weight of an ester of a starchy material, which has a degree of ester substitution (DS) of between 1.6 and 3, and at least 0.05% by weight and at most 99.5% by weight of a polymer other than starch.

A novel admixture for mineral binders is composed of a polyol composition with a high hydrogenated disaccharide content (&gE;40%). The hydrogenated disaccharide is advantageously chosen from maltitol, lactitol and mixtures thereof. Within the admixture, the polyol composition (for example, maltitol powder, a maltitol syrup or a hydrogenated starch hydrolysate) may be combined with conventional admixtures for mineral binders, particularly lignosulfonates. The hydrogenated disaccharides make it possible to obtain an excellent compromise between retardation, plasticity and the mechanical properties of the mineral binder. They may be used equally well for admixing with cements and raw materials for cements as for admixing with mortars, slurries and concretes.

The subject of the present invention is a sugar-free hard candy and a process which allows the manufacture of this candy. The sugar-free hard candy in accordance with the invention has a multilayer structure in which the external layer represents at most 35% of the candy, the said external layer consisting of at least two components A and B, component A being chosen from hydrogenated starch hydrolysates, xylitol, polymers of low-calorie saccharides or mixtures thereof, and component B being a weakly hygroscopic product.

Process of refining mixtures obtained from treatments of fatty media with cyclodextrin and containing complexes of cyclodextrin with lipophilic compounds of the fatty acid type, characterised by the fact that the said mixtures are subjected to a heat treatment at a temperature above 100.degree. C. in the presence of a solvent system containing water, that the various fractions or raffinates obtained from the heat treatment are separated and that these raffinates are recovered.

Process of refining mixtures obtained from treatments of fatty media

A process of refining mixtures obtained from treatments of fatty media with cyclodextrin and containing complexes of cyclodextrin with lipophilic compounds, characterized by the fact that the said mixtures are washed with at least one anhydrous polar solvent, whereby at least partial dissociation of the complexes of cyclodextrin/lipophilic compounds is brought about, and the lipophilic compounds which are not included are released from their connection with cyclodextrin.

Process of refining mixtures obtained from treatments of fatty media with cyclodextrin and containing complexes of cyclodextrin substantially with lipophilic substances other than fatty acids, characterized in that the said mixture is successively subjected to a heat treatment in the presence of a solvent system containing water, the mixture thus treated is separated into different raffinates and the raffinates are recovered.

Process for manufacturing products with a reduced content of sterols and particularly of cholesterol, characterized in that the starting material is composed at least in part of dairy cream and is in the form of an oil-in-water emulsion, and in that it consists essentially of:

Process for manufacturing dairy products with a reduced sterol content

The present invention relates to a process for preparing dairy products with a low content of sterols, particularly of cholesterol, characterized in that it consists essentially of contacting an oil-in-water emulsion comprising dairy fats with cyclodextrin in sufficient amount to form inclusion complexes with the sterols so that the latter can be extracted from the fat, and simultaneously or not, separating at least partly said complexes from the medium without inverting the starting oil-in-water emulsion.
